resty里请求域名地址时无法使用本地的`/etc/hosts`文件，需在`nginx.conf`文件中的`http`模块内添加`resolver`配置显式指定：

```nginx
http {
    ...
    resolver 8.8.8.8;
    ...
}
```

测试服所使用的DNS服务:

```bash
➤ ssh weli@moicen.com
Activate the web console with: systemctl enable --now cockpit.socket

# Generated by NetworkManager
nameserver 183.60.82.98
nameserver 183.60.83.19
[weli@moicen ~]$
```

put `upload.lua` into:

```bash
/usr/local/opt/openresty/nginx/resty_funcs
```

post file:

```bash
$ curl --location --request POST 'localhost/upload' \
--form '=@"/Users/weli/works/task_server/src/test/resources/file_example_JPG_100kB.jpeg"'
```

nginx config

```
/usr/local/etc/openresty/nginx.conf
```

```
location /upload {
   content_by_lua_file /usr/local/opt/openresty/nginx/resty_funcs/upload.lua;
}
```

enable log:

```
error_log  /usr/local/etc/openresty/logs/error.log;
```
